FINGER GUARD Filed May 10, 1 944 Hens BY wmwm H TTORNEY Patented July 3,1945 FINGER GUARD John B. Ghisnell, Barberton, Ohio, assignor to The SunRubber Company, Barberton, Ohio, a corporation of Ohio Application May10, 1944, Serial No. 534,863

1 Claim.

This invention relates to finger guards or finger pads.

An object of this invention is to provide a finger guard, of the typemade of rubber or like flexible, resilient material adapted to bereceived over the end of the finger, with improved means in the interiorthereof whereby is'assured circulation from end to end of the guard andwhereby is obviated or greatly reduced the usual discomfort caused byperspiration due to lack of air circulation insidethe guard.

Other objects of the invention will be manifest from the following briefdescription and the accompanying drawing.

Of the accompanying drawing:

Figure 1 is a side elevation of a finger guard of the type embodying theinvention.

Figure 2 is an end view as .viewed from the right thereof.

out filling the same or at least not to such an extent that passage ofair through the grooves will be prevented. To this end the bottom cor-.ners 14-, I4 of the grooves l2 may be relatively sharp or withoutsubstantial fillets, as illustrated in Figure 4. -Ihe grooves areunrestricted along the lengths thereof and communicate freely to r theextremity of the open end of the casing (see still further enlargedscale, taken at 4-4 in Fig- :5

ure 3.

Referring to the drawing, the numeral l0 designates a finger guard,which may be an elongated hollow casing of vulcanized rubber or otherflexible, resilient material, open at one end, and rounded at the otherend, and proportioned and shaped to be received on the finger withoutmaterially affecting bending action of the first joint of the finger.The outer surface of the guard or casing H1, at the rounded end thereof,is provided with a suitable non-skid design, as indicated at H, tofacilitate use of the guard as fo leafing papers or pages of a book.

The inner surface of casing l0 may have provided thereincircumferentially spaced, relatively narrow grooves l2, l2, which extendlongitudinally of the casing from the open end thereof to the inner orrounded end', these grooves defining relatively narrow ribs l3, l3. Thegrooves and ribs are'spaced substantially as shown so that when theguard is received on the finger the skin thereof will lay across thegrooves with- Figure 3).

in the use of theimproved finger guard it is adapted to be received overthe finger, substantially as shown in Figure 3, wherein a finger isshown in chain-dotted lines. As the guard is usually worn on the fingerso that there is a small space'or chamber at tip orrounded end, air isfree to circulate along grooves l2, between the open end of the guardand said spacev or chamber at the tip end. This circulation or airinside the guard prevents or materially reduces discomfort due toperspiration, as usually experienced by use of finger guards of knowntypes.

Modifications of the invention may be resorted to without departing fromthe spirit thereof or the scope of the appended claim.

What is claimed is:

A finger guard comprising a hollow elongated,

one-piece imperforate casing of rubber or like flexible, resilientmaterial, said casing being open at one end and adapted to be receivedon the finger, said casing being provided around the inner surfacethereof with circumferentially spaced ribs defining grooves therebetweenand extending longitudinally from said open end of the casing tosubstantially the length of the easing, said grooves being unrestrictedalong the lengths thereof and opening freely at said open end of thecasing, the inside corners at the bottoms of said grooves beingsubstantially sharp or without substantial fillets, whereby when theguard is received on the finger the skin will lie across the grooves andyet provide maximum continuous space along the grooves for freecirculation of air along the same and through the ends thereof openingat said open end of the casing.
